pH Meter Calibration Service in Bangladesh
ION Engineering calibrates laboratory and process pH meters against certified buffer solutions and traceable reference standards, accredited to ISO/IEC 17025:2017.
What We Calibrate
Benchtop pH Meters
Laboratory benchtop pH meters and electrode systems.
Portable pH Meters
Handheld and field pH meters used for on-site testing.
Process pH Analyzers
In-line process pH analyzers used in production and utility systems.
How We Calibrate a pH Meter
The meter is calibrated and checked against certified buffer solutions spanning its working range — typically acidic, neutral and alkaline points — with as-found and as-left readings recorded to confirm the electrode and meter combination reads accurately across the range you actually use.
What’s included
- Multi-point calibration with certified buffer solutions
- As-found and as-left readings, per point
- Stated measurement uncertainty
- QR-verifiable certificate
pH Meter Calibration FAQs
How often should a pH meter be calibrated?
Many labs calibrate before each use with buffer solutions and additionally have the meter formally calibrated and certified annually; the right interval depends on your quality programme.
Do you calibrate the electrode as well as the meter?
Yes, the meter and electrode are calibrated as the combination actually used, since electrode condition directly affects the result.
What measurement uncertainty do you report?
Uncertainty is stated per range on your certificate; our full accredited scope is published on our calibration capabilities page.
Is the certificate independently verifiable?
Yes, every certificate number can be checked using our online verification tool, with no login required.
